END-BINDER FOR THE RECORD-SHEETS OF PLAYER-PIANOS.

Specification of Letters Patent.

Patented Nov. 29, 1921.

Application filed September 30, 1920. Serial No. 413,670.

T 0 all whom it may concern.

Be it known that I, OTTO L. Koori, Jr., a citizen of the United States, residing at Woodlynne, in the county of Camden and State of New Jersey, have invented new and useful Improvements in End-Binders for the Record-Sheets of Player-Pianos, of which the following is a specification.

The ends of the record sheets used in player pianos have a highly objectionable tendency to curl and are susceptible of being easily torn, and the object of my invention is to )iOVlCl a binder which, in addition to preventing curling or tearing of a record sheet end, is adapted to contribute to the facility with which the said end can be handled by an operator.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, hereby made a part hereof;

Figure l is a plan view of the blank from which my novel binder is fabricated.

Fig. 2 is a )lan view showing the binder applied to a record sheet.

1 1g. 3 is a central transverse section taken in the plane indicated by the line 3-3 in Fig. 2.

Fig. i is a detail transverse section taken on the line indicated by the line -d of Fig. 2.

Similar numerals of reference designat corresponding parts in all of the views of the drawings.

At one end the record sheet 1 is tapered in accordance with the custom well known in the art.

My novel binder may be formed of any material compatible with its purpose. 1 prefer, however. to form the binder of linen provided with mucilage or other appropri ate adhesive at one side. The binder is com posed of a single blank, such as shown in Fig. l, and it is made of a body portion 2, arms 3 that reach from the body 2 and are disposed at approximate right angles to each other, and a tab e that reaches from the back edge of the body 2 in lapped relation to the inner ends of the arms 3 so as to strengthen and reinforce said ends. The arms 3 are folded upon themselves along the line 5, so that the adhesive, indicated by 6, will rest on the opposed sides of the folded arm portions. The tab 4 is bent upon itself, and the opposed portions produced in that manner are fastened together by appropriate means, as indicated by 7.

In applying the binder the body 2 is arranged at one side of the central portion of the end of a record sheet, and the arms 3 are made to straddle the end of a sheet, and are connected thereto in a strong manner by the adhesive alluded to.

The described formation of the tab 4 into a loop enables the tab to strongly hold a metallic finger piece such as shown at the lower ends of Figs. 2 and 3.

It will be apparent from the foregoing that in practice my novel binder will preclude the objectionable curling of the record sheet hereinbefore referred to and at the same-time will lend strength and durability to the said end so that the liability of the same being torn in use will be reduced to a minimum. Again, by grasping the tab or finger keys of the binder a person will be enabled to adjust the record sheet with great facility. 7

Having thus described my invention, what I claim and desire to secure by Letters Patcut, is I As a new article of manufacture, a onepiece record sheet binder, comprising a body, arms of comparative reduced width reaching laterally from opposite ends of the body and folded throughout their engths transversely upon themselves and having adhesive means at their inner sides to secure them on the end portion of a record sheet, and a tab reaching from the body and arranged in lapped relation to the inner ends of the folded portions of the arms; the said tab being folded lengthwise on itself to hold a finger piece and having its opposed portions permanently connected together by an eyelet to form the tab into a loop.

In testimony whereof I afiix my signature.

OTTO L. KOCH, JR.
